Value Collection 011427P Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 011427P is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural connections. It features a 5/8-11 UNC thread size with a 3-1/4 inch length under head and is partially threaded for positive clamping in through-bolt and tapped-hole applications. The screw is machined from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and a low-reflective surface. It drives with a 1/2-inch hex key and is manufactured to ASME/ANSI B18.3 and ASTM A574 standards. Machinists, millwrights, and maintenance technicians install this type of fastener in heavy-duty assemblies where a recessed drive and high tensile strength are required.

This socket cap screw is suited for use in industrial machinery, hydraulic fixture plates, jigs, machine bases, and structural steel fabrication where standard hex head fasteners are not practical. The socket drive allows installation in confined spaces where a wrench cannot swing freely. The partial thread design ensures that the unthreaded shank engages the clearance hole of the clamped material, providing accurate alignment and strong clamping force across the joint.

Key Features

• 5/8-11 UNC thread for high-load clamping in standard inch-series tapped holes
• 3-1/4 inch length under head with partial threading for accurate shank-to-clearance-hole fit
• Alloy steel construction meets ASTM A574 high-strength socket head cap screw specification
• Black oxide finish provides mild corrosion resistance and reduces surface glare
• 1/2-inch hex socket drive allows installation in tight or recessed locations
• Conforms to ASME/ANSI B18.3 dimensional standard

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any 5/8-11 UNC tapped hole requiring a partially threaded alloy steel fastener with a socket drive.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 1/2-inch hex key or socket-drive tool. Torque to joint requirements per applicable engineering specifications and do not exceed the rated proof load for ASTM A574 alloy steel socket head cap screws. De-energize, depressurize, or lock out equipment before servicing fastened assemblies per applicable OSHA lockout/tagout procedures. Inspect threads in the mating tapped hole for damage or contamination before installation.
